CHARLES C. WALLACE, OF ONEONTA, NEW YORK.

WHCIFFLET REE-HOOK.

SPECIFICATION forming part of Letters Patent No. 615,004, dated November 29, 1898. 7

Application filed September 21, 1898. Serial No. 691,601. No model.)

To all whom it may concern:

Be it known that I, CHARLES C. WALLACE, a citizen of the United States, and a resident of Oneonta, in the county of Otsego and State of New York, have invented certain new and useful Improvements in WVhiflietree- Hooks, of which the following is a full, clear, and exact description, such as will enable those skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification. 1

The invention relates to improvements in devices of that class in which the end of a trace,which is provided with a suitable opening for the purpose, is placed on an end of a Whiffietree and is held in place thereon by a hook secured to the whiifietree.

The invention consists in the novel construction, combination, and arrangement of parts, such as will be hereinafter fully described, pointed out in the appended claim, and illustrated in the accompanying drawings.

In the accompanying drawings, Figure 1 is a side elevation, partlyin section, of a device embodying the invention. Fig. 2 is a plan View of the same.

In both views like reference characters designate corresponding parts.

The whiffletree A may be of any construction suitable in the premises. As shown, it has a tapering end C6, provided with an aperture a, adapted to receive the free end of the retaining-hook. Inside of the aperture a a second aperture a is formed for the reception of the securing end of the retaininghook. The trace B is of a construction such as is in ordinary use. It is provided with an aperture 1), adaptedto receive the tapered end a of the whiffletree.

Secured on the end of the whiffletree is the trace-retaining device C. The latter is made of brass wire or other wire having the required resiliency. The hook is carried by the outer end of the shank c and has a projecting end 0 adapted to engage with the aperture a in the whiftletree. By reason of the engagement of the hook with the whiffletree the former is held against accidental displacement The distance that the end 0 can enter the aperture a is limited by the shank c contacting with the whiffletree. The bight c of the hook is of such a size as to fit over the edge of the trace, and thereby prevents the latter from moving on the end of the whiffletree in either direction. The book is normally held in engagement with the trace and the end 0 in register with the aperture a by a spring mechanism connected with the rear end of the shank c.

A spring D, formed of several coils d, is secured to the inner end of the shank and serves to normally hold the shank against the whiffletree and the hook in engagement with the trace. The coiled spring is carried by the arm d, and the latter is connected by the coiled spring d with the arm 01 The two arms 61 and (1 together with the connectingspring 01*, form a loop. The spring 01 forces the coil down upon the arm (Z and thereby increases the resiliency of the device.

The end (1 of the arm d is bent down at substantially right angles to the main part of the arm and is screw-threaded. The device is secured in place by screwing the end 01 into the aperture a of the whiffletree. If it is desired, additional strength to the fastening can be secured by turninga screw through the coil (Z into the whiftletree. Ordinarily, however, the latter will not be required.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is-

In a device for securing traces on whiffletrees, the combination of a hook, a shank carrying said hook, a coiled spring attached to said shank, an arm connected with said spring, a second coiled spring secured to the free end of said arm, a second arm carried by said second coiled spring and contacting with the under side of said first-mentioned coiled spring and having its free end bent at substant-ially right angles.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

CHARLES C. IVALLACE.
